Serial No. 660,085.

To ali whom it may concern Be it known that I, GEORGE lV. SWIFT, Jr.,

of Bordentown, in the State of New Jersey, 2

' engaging said roller; a pair of feed rollers extending horizontally transversely to the QQ- direction of movement of said feed plate; a

have invented a certain new and useful Improvenient in Blank-Feeding Mechanism,

whereof the following is a specification, reference being had to the accompanying drawings. n

, This ap lieation is a division of my aplo plicat-on gerial #650,492 filed September 21, 1911, for Letters Patent of the United States for an improvementin mechanism for making paper receptacles of the class described in Letters Patent of the United States #906,485 dated December 8,1908, su'h a vessel being seamlessly formed of a single primarily plane sheet and provlded with a wire bail handle havingvits ends clenched through the folds of the vessel so 2o as to retain the same in the desired shape.

Said mechanism for making paper receptacles includes a plane table upon which the fiat sheet blanks are placed, havinga horizo tal die opening through which said 2.1i sheets are successively pressed by a plunger `die, the folding of each sheet to proper form bein effected by said horizontal die during the through. Each receptacle thus thrust through the table is received in a holder of which there are four respectively mounted upon radial arms ony a rotary carrier by which they are successively presented to mechanism which provides them with the,

Wire bails aforesaid and mechanism .which discharges them upwardly from said holder.

My invention includes the various novel features of construct-ion and arrangement hereinafter described, comprising a horizon- 1o tal plane table; a stack holder arranged to' hold a stack of plane sheet blanks havingv marginal flaps, including opposite vertical angle bars fitted between'said fla-ps and having brackets at their lower ends connecting them with said table; a reciprocatory feed plate extending between the lower ends of said bars and the top of said table, arranged to support said stack whichgravitates thereon, and having abutments upon its upper surface arranged to eng/age and feed only the bottom blank in said stack, said plate and the bottom ends of said bars being so spaced as to permit passage of but a single 'blank between them; gear racks on said feed plate; gears engaging said racksyverplan view 'of said machine shown inFig. I "omitting the plunger die', etc. Fig. IV is a ownward movement of the sheet there# i tical shafts in said gears, havingfothergears beneath said table; a rack engaging said lower gears and having a cam roller; a cam vertically adjustable gate bar between said venting feeding movement of more than one blank at a time; and, means coperatively 6 5 gconnecting said' .plate and feed rollers t-whereby, blanks are deliveredl from sai stack singly, in succession.

In said figures;` the horizontal planev table 240 is provided with the stationary discom-` prising the four' plates 2, 3, 4 and 5; said plates. and 3 being rigidly connected there'- with by the screws 6 and 7 and said plates. 4 and 5 being adjustably connected with said table by the screws 8 and 9 extending through the respective slots 11 and`12 in saidplates. As best shown in Fig.l II the four plates of said stationary die are so corf related as to afford a vertical opening 14' therethrough having opposite lateral extensions 15 and 16. Said table 240 is rovided with the stops 241 adjoining said die,- ,100`

of saidblanks 20 between them. The recip- 1615.

rocatory feed plate 245, best shown in Fig. VIII extends between the lower ends -of said` bars 242 and the top of said table, 240, being arranged to support saidstack which gravitates thereon, and Ahaving abutments 11a 246 and 247 upon its upper surface arranged to engage and carry only the bottom blank in said stack, when said plate is moved toward said die; said plate and the bottom ends of said bars 242 being so spaced as to permit the passage of but'a single blank 20 between them. Said feed plate 245 is mounted to reciprocate in the bearings 249 on said table 240 and has the gear racks 250 engaging the gears 251 by which it is reciprocated. Said gears 251 are mounted upon the upper ends of the shafts 252 shown in Fig. VI, having at the lower ends thereof the gears 253 engaging the rack 254 which reciprocates on the bearing 255 rigidly connected with said table y240'. Said rack 254 is reciprocated by the engagement of its roller 257 in the cam 258 on the verticalshaft 259 which is journaled in the frame 260, and arranged to `be continuously rotated by the engagement of its gear 262 with the Worm'263 on the horizontal shaft 265 Which is journaled in the bearings 266 on said frame 260, and has the gear 267 engaging the gear 268 on the main .driving shaft 269 which is jpuignaledin the bearings 270 on said frame l260,:andA provided eX- terior thereto with the pulley 271. It may `be observed that said"sliaft l269 is' operatively, connected With a'fcain shaft extending parallel thereto and provided with cams and' adjunctive means arranged to operate the reciprocatory plunger die and bailing mechanism above mentioned. s shown in Figs. III, IV and V said vertical shaft 259 has the bevelggear 275 at the v`top thereof engaging the bevel gear 27 6 on the horizontal shaft 277 which is journaled in the bearings 278 'on said table 240, and has the bevel gear 280 engaging the bevel gear 281 on the shaft 282 of the feed roller 283 which is journaled in the bearing brackets 284 on said table 240 beneath the feed roller 285; the lat-ter being pressed into operative relation with the roller 283 by the springs 286 shown in Fig. VII.y Said feed roller 283 has the gear 287 engaging the gear l288 on the roller 285 to positively drive the latter.

Said feed rollers being continuously rotated in definite relation to the reciproca-r tory movements of said plunger die and said feed plate 245, catch the blanks 2O f as they are successively presented `by saidy plate and feed them into proper relationvvith the stationary die o-n said table 24d against said stops 241 shown in Fig. III. The 'feeding movement of more than one ofsa'id blanks 2O at a time is prevented by`4 the vertical gate bar 289 of said stack holder,`y`which is arranged to be raised and lowered in said bracket 284 `and may be verticallyadjusted by .the screw l290 Vand secured-` in adjusted position bythe nuts 291 'and set screw 292l shown in Figs. Vand VII, soas to afford passage for single' blanks 2O of different thicknesses beneath it. The outward return i movement of said feed plate 245 in frictional contact With the bottom blank in said stack of course tends to displace said bot- L tom blank outward. Therefore, I find it convenient to prevent such accidental dis-.

placement of the bottom blank in the stack cise details of construction kand arrange- .a ment herein set forth assit is obvious that' various i'nodicationsmay 'be made therein without departing from the essential features of"my inventionas defined in the, appended claims. l
